The temperature in fairbanks, alasks rose from negative one degrees fahrenheit to nine degrees fahrenheit. how many degrees did the temperature change?

There was 10° F change in temperature in Fairbanks, Alaska.

Step-by-step explanation:

Given:

Temperature change from = -1° F.

Temperature change to = 9° F

We need to find the change in temperature.

Change in temperature can be calculated by subtracting Temperature change from with Temperature change to.

Framing in equation form we get;

Change in temperature = Temperature change to - Temperature change from

Substituting the values we get;

Change in temperature =

Hence There was 10° F change in temperature in Fairbanks, Alaska.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
